Marvel revealed today that their next big event series will kick off with a bang – the death of Uatu the Watcher. Titled “Original Sin,” the series will be written by Jason Aaron with art my Mike Deodato Jr. and starting this May will run for eight issues over four months.

“It’s all the skeletons, all the dark things that you never know, all the interesting and intriguing information — not all of it even bad,” Marvel executive editor Tom Brevoort told USA Today. “And it will all expand out into dozens of stories that will cut to the core of who these characters are.”

Following the death of Uatu, the original Nick Fury will assemble a group including Captain America, Iron Man, Thor and others to find the culprit, while a second group consisting of the Punisher, Doctor Strange, Emma Frost, Ant-Man and Black Panther handle the investigation on their own.

In addition to the core title, the series will feature tie ins that include Wolverine and Spider-Man, as the Watcher’s killer has taken some of his precious artifacts, which has adverse affects on these heroes.

We’ll also see a zero issue for “Original Sin” in April, written by Mark Waid with art by Jim Cheung, that will focus on the relationship between Uatu and the new Nova, Sam Alexander, just before the Watcher’s death.

Aaron mentions that “Original Sin” is “not a game of Clue,” adding “It’s not just about guessing which one of these five people pulled the trigger. There’s a bigger overall mystery than that.”
